The magnetically coupled resonant wireless power transmission adopts DC chopper control over transmission power,while traditional DC chopper circuit switching has a high loss.This paper presents an improved circuit for a novel soft-switching BUCK DC-DC converter,where a coupled inductor,auxiliary inductor and diode are added to realize zero current switching-on and zero voltage switching-off.The converter has a simple structure and is easy to control.Furthermore,the paper describes the working principle and process of the circuit,designs circuit parameters,completes simulation and experimental research,and finally gives simulation and test waveforms.
